Research Select a topic that you find interesting, then learn as much as you can about it. This is called RESEARCH. Research is done by reading as well as by asking people in the know, such as your teacher, parents, librarian, etc… If you can think of an experiment to answer the questions, then you […]
Astronomy Science Project
Overview for an Astronomy Project Your entire project is about a science question you choose to solve. Thus, the project question is very important. The following gives you a “bird’s eye view” of how to select an astronomy question and how to evaluate the question. I. RESEARCH A. “Tinkering” Research or ” I Don’t Know […]
Cohesion: Surface Tension
What is Cohesion and How does it Relate to Surface Tension Cohesion is the attraction that like- molecules have for each other. Water molecules have an attraction for each other. This attraction is called cohesion. Surface Tension Surface tension is the skin-like surface of a liquid due to the cohesive forces between the liquid […]
Sound Facts
Sound is a form of energy produced by the vibrations (back and forth or to and fro motions) of a material. Sound is energy that can be heard by the human ear. It takes energy to produce a sound. For example, the test tubes shown in the photo are filled with different amounts of colored […]
Engineering Project Winner
GARRETT YAZZIE Garrett participated for the first time in the third annual Arizona American Indian Science and Engineering Fair (AISEF). He made a solar powered heater out of aluminum cans and a car radiator from an old Pontiac, which he found at a junkyard. He says his mother and his science teachers influenced him the […]
Black Hole Facts
A black hole starts out as a star, which is very large. Stars give off light because of the nuclear reaction in its core. This reaction produces massive amount of energy resulting in extreme temperatures. The motion of particles increases with an increase in temperature. The kinetic energy of these particles is in an outward […]
Sound Facts
Sound is a vibration in an elastic material that is capable of being heard by the human ear. Vibration is a back and forth motion. Elastic is the ability of a material to compress and expand . Sound energy moves as a wave, thus is called sound waves. These waves cause a material to compress, […]
Good vs. Bad Acoustics
Acoustics has two meanings: (1) The science of acoustics is the study of sound, which deals with the production and transmission of sound. (2) The acoustics of a room indicates how sound acts in a room. Acoustical engineering understand the science of acoustics and use this knowledge in designing and building structures with specific acoustics. […]
Scientific Method: Outline
What is the Scientific Method? The scientific method is a basic outline that is required for for science fair projects. The steps in this outline were determine by observing the work of successful scientists of the past and they are still in use today. The steps shown here are in an order suggested for developing […]
Simple Leaves vs. Compound Leaves
The diagram shows two types of leaves: Simple Leaves: A single leaf is attached to the stem. While most are attached by a petiole, it could be directly attached without a petiole. Compound Leaves : The petiole of each compound leaf is attached to a petiole-like midrib, which, in turn, is attached to the stem. […]
